Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lifting device for covering soil in a multi-film laying device.

Cultivated soil cultivated by rotary tillage equipment,
A mulch constructed by forming multiple ridges with a ridge tool, laying mulch film on these ridges, lifting up cultivated soil at the soil lifting section, and covering the area around the ridges and grooves at the soil distribution section. The applicant filed a patent application for the film laying device in 1982.
This is proposed in No. 058999, etc., and it is possible to form multiple ridges and cover them with soil at the same time, making it an excellent method for saving labor and improving work efficiency. . Since the process from forming ridges to covering with soil is carried out in one work step, it is necessary to devise measures to ensure that the tilled soil for forming ridges does not run out due to the lifting of soil for covering.

Therefore, the present invention has been devised so that the ridge formation can be carried out without any problems and the necessary soil for covering can be secured, and for this purpose, the following technical measures have been taken. That is, the rotary tiller, which is connected to the rotary tiller so as to be movable up and down by a traction machine, can be rotated and fixed to either the left or right center portion of the rotary tiller via a connecting rod, a link mechanism, etc. Each ridge is formed by a plurality of ridge makers which are provided with a connected soil lifting section, a multi-film laying section, and a soil distribution section, and which are provided at the rear of the rotary tillage device so as to be movable left and right. In addition, a mulch film is constructed such that the mulch film is laid in the ridges by the mulch film laying device, and the cultivated soil lifted up by the soil lifting section is covered in the vicinity of the ridges and grooves by the soil distribution section. A mulch laying device, characterized in that the soil taking-in portion of the soil lifting section is located on the back side of the cultivating body, and is provided near the furrow forming section in front of the ridge erecting device. It is an object of the present invention to provide a lifting device for covering soil in a film laying device.

With this configuration, the present invention was able to obtain the following technical effects. That is, since the soil taking-in portion 21a of the soil lifting section 21 is located on the back side of the tiller 32 and near the front of the ridge forming section 33a in front of the ridge erector 33, the tiller 32 Therefore, the cultivated soil thrown backward can be directly put into the soil-lifting section 21a, thereby making it possible to uniformly stabilize the soil-lifting performance of the soil-lifting section 21. In the vicinity where the lifted soil is taken in by the soil intake portion 21a, furrows A that do not require tilled soil are formed, so there is no fear that tilled soil will be insufficient to form the furrows C. Moreover, furrow A
Since the cultivated soil in the area where the ridges are to be formed is removed by the soil removal section 21, the forming work of the ridges A and ridges C can also be carried out smoothly.

Next, to explain one embodiment of the present invention, as shown in a side view in FIG. 1 and a rear view in FIG. The hit part 5 of the machine frame 6 is connected to the hit part 5 of the connecting rod 4 of the rotary tillage device 3, which is connected so that the base plate 8 is fixed to the horizontal rod 7 of this machine frame 6. The front part of the main link 12, in which the holder plates 9 and 10 are connected by a holder 11 having a rectangular frame shape in plan view, is pivoted to the base plate 8 using a fulcrum pin 13, and a vertical axis is attached to the rear part of the main link 12. The rotating tip of the link 15 pivotally connected at 14 and the side end of the base plate 8 are connected to the sub link 16.
are connected using pins 17 and 18 to form a parallel link mechanism 19 consisting of the main link 12, sub link 16, base plate 8, and link 15, and the base plate 8 has a central pin hole 8a and left and right pin holes 8b. , 8c, and insert the pin 20 by aligning the pin hole 9a provided in the holder plate 9 with the pin hole 8a of the base plate 8, the parallel link mechanism 19 is formed as shown in a plan view of the main part in FIG. is fixed at the center position in the left and right direction of the rotary tiller 3, and when the pin 20 is inserted into the left and right pin holes 8b and 8c, for example, the left pin hole 8b and the left pin hole 9a, the position shown in FIG. As such, the parallel link mechanism 19 is configured such that its rear portion is fixed in a position swung to the left. Next, an embodiment of the structure in which the soil lifting section 21, the film laying section 22, and the soil distributing sections 23, 24, and 25 are attached to the respective positions of this parallel link mechanism 19 will be explained. Then, the soil lifting section 21 is constructed by inserting the frames 28, 28 on which the pulleys 26, 27 are mounted above and below into the holder 11 and attaching them to the holder 11, and attaching the lugs 29... or the belts on which the buckets are arranged. 30 to pulley 26,
27, and the belt 30 is driven as shown in FIG. A plurality of furrow tools 33 rotate in the arrow direction and are located behind the cultivating body 32.
33...1 ridge maker 33 (center left and right in the illustrated example)
From the soil taking-in portion 21a of the soil lifting section 21, which is visible near the front of the ridge forming section 33a, the tilled soil is scooped up onto the belt 30 by the lugs 29, and the soil is lifted up. The lifted soil is discharged to a guide cover 34 near the pulley 26, and the discharged lifted soil is guided to a popper 35 by the guide cover 34.

In the illustrated example, the soil lifting section 21 and the ridge raising device 33 are mounted on a vertical rod 48 fixed to the frame 7, and the ridge is mounted on a horizontal rod 36 fixed to the lower part of the vertical rod 48. A rolling wheel 37 that rolls on the groove A is mounted on a shaft, ridge standers 33, 33... are attached to the horizontal rod 36 so as to be adjustable in left and right positions, and an arm 38 is extended forward to the ridge plate 33 in the center of the left and right sides.
